       5. The device of  claim 1  wherein the extension member is constructed of polyvinyl chloride (PVC) pipe. 
     
     
       6. The device of  claim 1  wherein the proximate end of the extension member has an aperture for the passage of the wires, said aperture being fitted with a rubber grommet. 
     
     
       7. The device of  claim 1  wherein the extension member is comprised of a first component and a second component, with the first component being removably attached to the second component, such that detaching the first component from the second component provides access to the hollow interior of the extension member. 
     
     
       8. The device of  claim 1  wherein the wires comprise a positive lead, a negative lead, and an inline fuse integrated with the positive lead. 
     
     
       9. The device of  claim 1  further comprising a handle, the handle integrated with the extension member. 
     
     
       10. The device of  claim 9  wherein the handle extends substantially perpendicularly from the extension member at a location at or near the distal end of the extension member. 
     
     
       11. The device of  claim 9  wherein the switch is located on the handle. 
     
     
       12. A cordless portable pump device comprising
 a submersible pump having a housing and an electric motor contained within the housing, the pump being suitable for taking in a fluid substance into the housing and expelling the fluid substance from the housing; 
 wires capable of conducting electrical current; 
 a power supply,
 the power supply comprising a rechargeable battery pack from a commercially available portable power tool having a voltage rating of at least fourteen volts, and 
 the power supply having an insertion member, the insertion member having one or more electrical contacts thereupon, said one or more electrical contacts being in electrical engagement with the rechargeable battery pack; 
 
 a power receptacle,
 the power receptacle being in connection with the electric pump motor by the wires, 
 the power receptacle being suitably adapted to receive and retain the insertion member of the power supply, and 
 the power receptacle having one or more electrical contacts, with the one or more electrical contacts of the power receptacle suitably adapted to engage with the one or more electrical contacts of the insertion member of the power supply to establish an electrical connection from the power supply to the electric pump motor through the wires; and 
 
 one or more adapters, each said adapter being suitably configured to be inserted into the power receptacle and further being suitably configured to receive and retain the insertion member of the power supply, such that each said adapter provides an interface between the power supply and the power receptacle, with each said adapter configured to conform to a specific commercially available rechargeable battery pack for a portable power tool, whereby different commercially available rechargeable battery packs may be used with the device when coupled with an appropriately configured adapter.
